Procedure

14.1 parts of 3-methoxy-2-cyanodihydrothiophene in 80 parts by volume of chloroform are reacted with 6.75 parts of sulfuryl chloride in 20 parts by volume of chloroform for 0.5 hour at 0° C. The end product is isolated from the reaction mixture by the method described in Example 14c). 12.6 parts (91% of theory) of 3-methoxy-2-cyanothiophene of boiling point 73° C./0.16 mbar are obtained.
